Abstract

a. Procédé et installation pour la fabrication d'éléments creux en béton armé. b. On utilise, pour former les alvéoles de l'élément, des noyaux réalisés en une matière solide à la température ambiante, mais qui est susceptible de se liquéfier à plus haute température, afin d'être récupérée à travers de petits orifices ménagés à cet effet dans le béton lors de son coulage. c. Fabrication de dalles comprenant une chape inférieure faisant office de faux plafond
